ISLANDS-CAYOS :
Isla de la Juventud and a large part of gulf of Batabanó (turquoise blue), plus east end of cayos San Felipe on the left edge of the picture, cayos Los Indios between those and isla Juventud, and the many cayos located north and north-east of isla Juventud (Canarreos Archipelago). North side of Juventud, vhere the turquoise blue is clearest between this island and mainland Cuba, are a series of four small cayos that include cayo La Grifa and cayo Cuarto.
The right edge of the picture closely matches the south-eastern limit of Artemisa Province with Mayabeque Province's south-western limit.

Coming from the east, two cayos look like they are nearly reaching mainland Cuba.

The first of these that we meet, stands with its north end pointing at a small advance of the land into the sea in Guira de Melena municipality; googlemaps calls that little cape Punta de Cayamas. To the island itself, googlemaps gives no name. Nor does mapcarta.com.

openstreetmap calls it cayeria Las Cayamas and shows it in Artemisa Province.

The next cayo to the east is into two parts, one to the north of the other, on divided the map in googlemaps - but a satellite view of that same map shows that a series of six tiny islets closely links both parts.

That same map calls the northern part cayo Guzmán and either gives no name to the southern part, or gives the name to both parts.

openstreetmap calls the northern part cayo Punta Tierra del Guzman and the southern part cayo Guzman.

mapcarta.com, like openstreetmap, places the name "cayo Guzman" on the southern part and, conversely with googlemaps, does not give a name to the northern part.

MAINLAND COAST, west to east:
missing La Coloma by a hair's width, we can see the tail end of Ensenada de La Coloma (Pinar del Río municipality) in upper left corner.
Next right, lined with white, is Punta de Fisga (on googlemaps) or Punta la Fija (on openstreetmap), (Pinar del Río municipality). Promptly followed by Consolación del Sur municipality (Pinar del Río province).
Playa de las Tunas.
Punta de la Vijia (googlemaps) or Boca de San Diego (openstreetmap), followed by :
Ensenada Dayaniguas with Playa Dayaniguas, followed by Laguna Media Casa (looks like a quarter moon with the bulging side pointing south an lined with white). 15 km further along the coast comes the San Cristóbal municipality (Artemisa province), with a small notch in the coast where Santa Rosa is.
The next notch, more visible, is El Francés. About 7 km further is Candelaria municipality's coast for some 6 km, followed by Artemisa municipality.
North is off to the right, pointing from the middle of Juventud to where the pack of clouds up right is the thickest.
